Abstract

The invention relates to an artificial hip joint acetabular cup. The artificial hip joint acetabular cup is shaped like a concave semicircle arc, the artificial hip joint acetabular cup comprises an outer layer, an inner layer, an acetabular cup lining and a lining shell, wherein the outer layer and the inner layer are fixed into a whole; the lining shell wraps the acetabular cup lining, the outer side of the lining shell is locked with the the surface of the inner layer, and the inner side of the lining shell is matched with the acetabular cup lining; the inner lining shell is made of polyether-ether-ketone or derivatives of the polyether-ether-ketone. According to the artificial hip joint acetabular cup, the inner layer is combined with the acetabular cup lining through the lining shell which is made of the polyether-ether-ketone (PEEK) or the derivatives of the polyether-ether-ketone, stress concentration is reduced, and the rigidity of the acetabular cup is increased properly; due to the fact that the lining shell which is made of the PEEK or the derivatives of the PEEK wraps the acetabular cup lining and then is combined with the inner layer, the matching requirements of a hard lining can be met, and the matching requirements of a soft lining can be met.

Description

一种人工髋关节臼杯 An artificial hip joint acetabular cup

技术领域 FIELD

[0001] 本发明涉及一种医疗康复器械,更具体地,涉及一种人工髋关节臼杯。 [0001] The present invention relates to a medical rehabilitation equipment, and more particularly, to a prosthetic hip cup.

背景技术 Background technique

[0002] 近年来新一代髋关节白杯假体普遍采用一杯多衬的设计,即白杯能同时接受软内衬(UHMWPE 内衬,Ries MD.Review of the evolut1n of the cementless acetabularcup.0rthopedics.2008Dec ;31(12Suppl 2).pi1:orthosupersite, com/view, asp ? rID=37178.Review.)和硬内衬(陶瓷内衬,Chotai PNl, Su EP.0rthopedics.20110ct5 ;34(10):e682-4.do1:10.3928/01477447-20110826-30.Fracture of a titaniumsleeve-encased third-generat1n ceramic liner in a modern THA,或金属内衬)。 [0002] In recent years, a new generation of white hip cup prosthesis commonly used multi-cup lining design, i.e. white cup can also accept a soft liner (UHMWPE liner, Ries MD.Review of the evolut1n of the cementless acetabularcup.0rthopedics.2008Dec ; 31 (12Suppl 2) .pi1:?. orthosupersite, com / view, asp rID = 37178.Review) and hard lining (ceramic lining, Chotai PNl, Su EP.0rthopedics.20110ct5; 34 (10): e682- 4.do1: 10.3928 / 01477447-20110826-30.Fracture of a titaniumsleeve-encased third-generat1n ceramic liner in a modern THA, or a metal liner). 但是这两种内衬对锁合结构有截然不同的要求,其中软内衬要求尽可能的外侧球面无缝接触臼杯内壁,从而消除水栗效应及保证内衬壁厚度最大化,而硬内衬则要求内衬外侧边缘锥面与白杯内壁锥面锁合。 However, both lined for closure structures have very different requirements, which calls for a seamless soft liner in contact with the inner wall of the cup outside the sphere as much as possible, to eliminate water chestnut lining wall thickness to maximize the effects and ensure that, while the inner hard It requires liner lining the outer edge of the tapered inner wall of the tapered locking white cup.

[0003] 对于不同的病人而言,有的适合于接受软内衬的白杯,有的适合于接受硬内衬的臼杯,然而,对于硬内衬的白杯而言,硬内衬特别是陶瓷内衬对白杯的变形而形成的应力集中特别敏感,为了防止硬内衬对白杯的应力过大导致白杯破损,往往将白杯的边缘厚度最大化来增加白杯的刚性。 [0003] for different patients, some adapted to receive soft-lined white cup, some adapted to receive a hard-liner of the cup, however, for the hard-lined white cup, especially hard-liner stress concentration is particularly sensitive to modification white ceramic cup liner formed, in order to prevent stress hard white cup liner is too large white cup breakage, they tend to maximize the edge thickness white cup white cup to increase the rigidity. 然而,这样的做法不仅繁琐,而且往往会导致制作成本较高等一系列缺陷。 However, such an approach is not only cumbersome, and often result in higher production costs and a series of defects.

[0004] 因此,一种新的接受硬内衬的人工髋关节臼杯是期望的。 [0004] Therefore, a new liner receiving hard artificial hip acetabular cup is desired.
